My invention particularly relates to a wheel dresser assembly comprised of aplurality of series of disks of diiterent sizes. In the accompanying drawings and the descriptive detail hereinafter given I show and describe two series of such disks arranged in alternate. relation. .The purpose of the invention is to provide adisk construction and assembly that will present dressing teethV capable of effecting a picking action even after considerable service and at a time when the teeth would presumably be worn down so as to present flat surfaces. This is effected by bringing the unimpaired teeth of the smaller disks into play vafter the teeth of the larger'disks have been worn down. The im.

proved `assembly is adaptable for use as a dressing tool as well as for use as a picking machine.

The annexed drawings and the following description set forth in detail certain means embodying my invention, such disclosed means, constituting, however, but one of the various forms in which the principle of the invention may be illustrated.

In said annexed drawings: Fi 1re 1 is a side elevation of my improved dressing wheel assembly rotatably mounted in a bracket adapted to be lixed t0 a recipro- Y eating slide :torvfeeding `the dresser across the grinding face of an abrasive wheel, to effect a dressing action in `amanner well known to those skilled in the art;

' During the dressing operation al picking actionby pointed teeth is desirable and'in the 'standard construction'of dresser assemf blies such picking Yaction isobtainable only Y while, the points of the teethare comparatively sharp. Consequently, so soon as the points are worn down to present a flat surfaceto the grinding wheel face this desirable picking action is'eliminated. 'Howeveiu by my improved assembly, the points of the teeth 7 of the smaller `disks Q takeup and continue the desirable picking action at a time when the ends of the teeth 6 of the larger disks 1 are worn down so as `to present a surface so lat as not to furnish this pickino' action.
